Igo Shinan '92, released in Japan, continues the Igo (Go) game series on the NES. It likely incorporates improvements or new features compared to its predecessor, Igo Shinan '91.   Gameplay retains the emphasis on strategic board play inherent in Igo.  Lack of readily available information on the specifics of development and sales does not diminish its importance in the context of the NES's software library.
